Neanderthals, which were traditionally thought of as extremely primitive humans, are now believed to have been extremely intelligent, even comparable to the intelligence of modern humans. They used tools, had social structures, thrived in hostile environments, and lived long lives.
Humans almost became extinct about 70,000 years ago when the total population dropped below 2,000.
Humans are 99.9% genetically identical to each other. The 0.1% difference account for the various differences, like skin color, hair color, eyes, and even diseases.
Contrary to what you might think, the cranium isn’t made out of just one bone. The human skull consists of twenty-two bones – eight cranial bones and fourteen facial skeleton bones. Except for the jaw, all of these bones are fused together by sutures (immovable joints), hence they tend to act as one.
Humans make up just 0.01% of all life but have destroyed 83% of all known wild mammals.

In 1963, the Bronx Zoo had an exhibit called “The Most Dangerous Animal in the World”. It was a mirror.
Back in the early 1980s, orthodontist David Marshall, from Syracuse, NY, liked to speculate about what humans would look like 2 million years in the future. Or what “Future Man” would look like, as he referred to our descendants. Based on previous trends in our evolution, he concluded that Future Man will be hairless, big-skulled, small-jawed, and have few teeth.
Dean Karnazescan can run without ever getting tired due to his exponentially high lactate threshold. He was able to run a Marathon in the south pole at -25C and run for three consecutive nights before having to stop for sleep.
Shakuntala Devi, also known as the human computer, gave the 23rd root of a 201 digit number in 50 seconds. The answer(546,372,891) was verified at the US Bureau of Standards by the UNIVAC 1101 computer, for which a special program had to be written to perform such a large calculation.
Of all the humans tested so far, everyone has contained the same DNA from 1 of at least 2 ancestors. Mitochondrial DNA being traced back matrilineally to a specific “mT-Eve,” and a Y-chromosome being traced back patrilineally to a specific “Y-chromosomal Adam.” We are not descended from a singular couple, but rather we are all seemingly descended from singular ancestors that may have lived hundreds of thousands of years apart.
